利用JS实现简单的日期选择插件
人气:0首先是调用方法如下
//调用方法，后面回调函数返回的是当前选择的日期
calender('#calend').init(function(date){
this.innerHTML = date
});
//具体参数说明
//如果需要传入参数，第一个为json，第二个为回调函数
//下面是format格式化显示格式类型，有如下几种：
//yyyy为年数
//大写M为月数
/https://img.qb5200.com/download-x/d为几号
//h为小时
//小写m为分钟
//s为秒数
//q为季度
//小写e，为数字星期格式
//大写E，为中文星期格式
//举例：'yyyy年MM月dd日','yyyy-MM-dd','yyyy','MM','e','dd E'
//注意：以上获取时间如果是个位数则返回个位数，比如7月，则返回7，如果需要返回07，参数可以写成这样“MM”，其它同理，由于时分秒功能还没有添加，默认获取当前时分秒
calender('#calend').init({
date : [2015,12,12], //设置默认显示年月日，默认当前年月日
format : 'yyyy-MM-dd', //设置显示格式
button : false //是否显示按钮
left : 0, //追加left，默认0
top :0, //追加top，默认0
onload : function(){ } //初始化完成执行，this为当前创建的日历对象
},function(date){
//回调函数
this.innerHTML = date
});
